Despite what was said earlier, IPv4 Auto, IPv6 Ignore (try it later but for now off). In IPv4 tab, 'Connect Automatically' box ticked and 'Require IPv4 addressing ...' unticked.
This is a modem router or just a modem? You are plugged into the modem? If that is the case, if you have the IP address of the modem you could try pinging it in a terminal by:
... replacing the number with the IP address of the modem (which will have same syntax). That should show signs of life if at least that much is working. If it is then can start working out why you're not getting out. Yes, could be DNS issue.
If you are plugged into modem; can you get to the configuration by putting its IP address into a web browser? You might have to tweak something on the modem.
This is a new setup, right? So it wasn't 'working fine before' with this hardware?
